Apparently CoolerMaster is coming out with a closed loop watercooling solution to beat the H80/H100 and anything else like that. Get a load of this:
CeBIT 2012 - Cooler Master Upcoming Products Preview - Cooler Master Eisberg 120 and 240
Standard 120mm/240mm radiators, coiled spring reinforced tubing, and a very good pump/cpu block with the pump being made by Eheim (big name in aquatics). Fully expandable and the pump can apparently feed 8 blocks?
